The service platform delivery system 40 functions as an integrated base that provides a common service such as a workflow related to the authentication/authorization and the image process, and as a service group that provides an application service such as a scan service and a print service by utilizing the function of the integrated base.

The integrated base is, for example, constituted of the common service 102, the data base 103 and the platform API 104. The service group is, for example, constituted of the application 101. Thus, the service platform delivery system 40 illustrated in FIG. 5 is configured to have the service group separated from the integrated base.

Because the service platform delivery system 40 is configured to have the service group separated from the integrated base, the application 101 that utilizes the platform API 104 can be readily developed. Moreover, the service platform delivery service 40 illustrated in FIG. 5 can readily develop a service delivery device such as the translation service delivery device 32 utilizing the platform API 104.

Here, a classification form of the process blocks of the service platform delivery system 40 illustrated in FIG. 5 is an example, and classifying the application 101, the common service 102 and the data base 103 according to a hierarchy illustrated in FIG. 5 is not required.

The job execution management unit 204 makes a job execution request to the scanner application 206 upon determining that the authorized token is valid.

The scanner application 206 determines whether to have an authority needed to process the job execution request, and executes the job depending on the job execution request upon determining that the scanner application 206 has the authority to execute the job execution request. The scanner application 206 causes the OCR application 207 to perform the process upon determining that the process by the OCR application 207 is needed to execute the job.

<Details of Process>

A description is given below of a processing procedure when utilizing a translation service through the image forming apparatus 12 of the information processing system 1 according to the first embodiment.

<<Overall Sequence>>

FIG. 7 is a sequence diagram illustrating an example of a processing procedure for utilizing a translation service in the information processing system according to the first embodiment. A user who operates the image forming apparatus 12 requests the browser 201 to display the translation application 202 by operating the browser 201.

The browser 201 displays a login screen to allow a user to input necessary information to login on the operation panel 602, and receives an input of a mail address and a password from the user as an example of the necessary information to login.

In step S11, the browser 201 receives the input of the mail address and the password from the user, and then requests the translation application 202 to login when, for example, a login button or the like is pressed down by the user.

In step S12, the translation application 202 requests the ID management service unit 220 of the service platform delivery system 40 to login by specifying the mail address and the password. Here, the ID management service unit 220 corresponds to the authentication/authorization unit 131, the user management unit 133 and the license management unit 134 of the service platform delivery system 40. The ID management service unit 220 authenticates the user by using the mail address and the password specified in step S12.

Upon succeeding in authenticating the user, the ID management service unit 220 issues an authentication ticket and notifies the browser 201 and the translation application 202 in the image forming apparatus 12 of the authentication ticket. The browser 201 displays a screen of the translation application 202.

The user operating the image forming apparatus 12 requests to execute a job utilizing the translation application 202 by operating the browser 201. In step S13, the browser 201 requests the translation application 202 to execute the job.

Here, it is assumed that functions of the scanner application 206 and the OCR application 207 of the image forming apparatus 12 are needed to be utilized to execute the job of the translation application 202. Moreover, it is assumed that an authorized token issued from the ID management service unit 220 is needed to utilize the functions of the scanner application 206 and the OCR application 207.

In step S14, the translation application 202 requests the translation service delivery device 32 to obtain the authorized token by specifying the authentication ticket. In step S15, the translation service delivery device 32 requests the ID management service unit 220 to obtain the authorized token by specifying the authentication ticket, and an application ID and an application password of the translation service.

The ID management service unit 220 issues the authorized token by utilizing the authentication ticket, and the application ID and application password of the translation service. The ID management service unit 220 notifies the translation application 202 in the image forming apparatus 12 of the authorized token by way of the translation service delivery device 32.

In step S16, the translation application 202 requests the controller 601 that executes the scanner application 206 and the OCR application 207 to perform a scanning process and an OCR (optical character recognition) process by specifying the authorized token. In step S17, the controller 601 verifies the authorized token, and determines whether to have an authority to utilize the functions of the scanner application 206 and the OCR application 207.

Upon determining that the authorized token has the authority to utilize the functions of the scanner application 206 and the OCR application 207, the controller 601 performs the scanning process and the OCR process in step S18. The translation application 202 reflects an execution result of the scanning process and the OCR process by the controller 601 on the screen displayed by the browser 201.

Here, a variety of configurations are conceivable with respect to the authorized token of the present embodiment as described later. The verification of the authorized token in step S17 varies depending on the configuration of the authorized token as described later.

<<Platform API Calling Relationship>>

FIG. 8 is a diagram of an example for explaining a calling relationship of the platform API 104 between the image forming apparatus 12. The translation application 202 of the image forming apparatus 12 requests the ID management service unit 220 to obtain the authorized token by way of the translation service delivery device 32. In the meanwhile, an external application 231 or a Native application 232 of the image forming apparatus 12 requests the ID management service unit 220 to obtain the authorized token.

The Native application 232 contrasts with a Web application, and is a type of application that causes the image forming apparatus 12 to perform a main process. The Web application is a type of application that causes the service delivery system 30 or the service platform delivery system 40 to perform the main process.

As illustrated in FIG. 8, the translation application 202 that operates on the browser 201 does not directly utilize an authorized token acquisition API but utilizes the authorized token acquisition API by way of the translation service delivery device 32. This is because authentication information for application authentication (application ID, application password) is more likely to leak when the translation application 202 implemented by HTML, JavaScript 203, CSS (Cascading Style Sheets) and the like has the authentication information for application authentication. In contrast, because the Native application 232 can retain the authentication information for application authentication in secret, the Native application 232 is allowed to directly utilize the authorized token acquisition API.

<<Details of Process of Image Forming Apparatus During Job Execution>>

FIG. 9 is a sequence diagram of an example illustrating details of a process of the image forming apparatus when executing a job. In step S31, a user operating the operation panel 602 of the image forming apparatus 12 requests a job utilizing the translation application 202 by operating the browser 201. In step S32, the browser 201 requests the translation application 202 to execute the job.

In step S33, the translation application 202 requests the JavaScript 203 to issue an authorized token by specifying request time and an authentication ticket. In FIG. 9, a depiction of the authentication ticket is omitted. The request time specified at this time is utilized to set an expiration date of the authorized token in the ID management service unit 220.

In step S34, the JavaScript 203 requests the translation service delivery device 32 to obtain the authorized token by specifying the request time and the authentication ticket. In step S35, the translation service delivery device 32 requests the ID management service unit 220 to obtain the authorized token by specifying the request time and the authentication ticket specified by the JavaScript 203, and an application ID and an application password of the translation service.

In step S36, the ID management service unit 220 issues the authorized token by utilizing the specified request time and the authentication ticket and the application ID and the application password of the translation service.

For example, the ID management service unit 220 sets the time after a predetermined period of time (e.g., one hour later) from the specified request time for an expiration date of the authorized token, into the authorized token. Here, the request time of the service platform delivery system 40 is not used to set the expiration date but the request time specified by the image forming apparatus 12 is used to set the expiration date because the time may not be synchronized with each other and the image forming apparatus 12 checks the expiration date, not the platform delivery service 40. Accordingly, when the time is synchronized with each other, the ID management service unit 220 may set the expiration date of the authorized token by utilizing the request time of the service platform delivery system 40.

The ID management service unit 220 notifies the translation application 202 and the JavaScript 203 in the operation panel 602 of the issued authorized token by way of the translation service delivery device 32. In step S37, the translation application 202 requests the JavaScript 203 to execute the job by specifying the authorized token. In step S38, the JavaScript 203 requests the job execution management unit 204 of the controller 601 to execute the job by specifying the authorized token.

In step S39, the job execution management unit 204 requests the authorized token verification unit 205 to verify validity of the authorized token by specifying the notified authorized token. The authorized token verification unit 205 verifies the validity of the authorized token, and returns a result of the validity verification to the job execution management unit 204. Here, the validity verification of the authorized token performed by the authorized token verification unit 205 may include a check of whether the authorized token has been issued from the ID management service unit 220 in addition to a check of the expiration date.

The check of whether the authorized token has been issued may be performed, for example, in a manner such that the image forming apparatus 12 and the ID management service unit 220 have a common key and the image forming apparatus 12 decrypts the contents encrypted by the ID management service unit 220. When the image forming apparatus 12 can decrypt the contents encrypted by the ID management service unit 220, the authorized token is guaranteed to be issued from the ID management service unit 220. Here, the check of whether the authorized token has been issued from the ID management service unit 220 may be performed by utilizing an electronic signature or a public key.

In step S40, the job execution management unit 204 requests the scanner application 206 to execute the job by specifying authorization information. Here, the authorization information is information contained by the authorized token and to determine whether to have an authority to utilize a function of the image forming apparatus 12.

In step S41, the scanner application 206 determines whether to have the authority to utilize the function of the image forming apparatus 12 based on the authorization information. Details of a process in step S41 is described later.

Upon determining that the scanner application 206 has the authority to utilize the function of the image forming apparatus 12, the scanner application 206 executes the job in step S42. The scanner application 206 returns the execution result of the job to the job execution management unit 204. The job execution management unit 204 returns an execution result of the job to the translation application 202 and the JavaScript 203, and reflects the execution result of the job on the screen displayed by the browser 201.

<<Details of Process of Translation Service Delivery Apparatus and ID Management Service Unit in Issuing Authorized Token>>

FIG. 10 is a sequence diagram of an example illustrating details of a process of the translation service delivery device 32 and the ID management service unit 220 when issuing an authorized token. In step S61, the translation service delivery device 32 requests the ID management service unit 220 to obtain an authorized token by specifying the request time and the authentication ticket specified by the image forming apparatus 12, and the application ID and the application password of the translation service.

FIG. 11 is an explanation drawing illustrating an example of contents included in an authorized token acquisition request. The authorized token acquisition request illustrated in FIG. 11 includes an application ID, and application password, an authentication ticket, and requested time.

In step S62, the authentication/authorization unit 131 of the ID management service unit 220 performs application authentication by using the application IF and the application password, and obtains a service name after normally finishing the application authentication. The application authentication in step S62 is a process for limiting the application that can utilize the authorized token acquisition application API in step S61. In step S63, the authentication/authorization unit 131 verifies the authentication ticket, and obtains a user ID after normally finishing the verification of the authentication ticket.

In step S64, the authentication/authorization unit 131 makes a user information acquisition request to the user management unit 133 by specifying the user ID obtained in step S63. The user management unit 133 specifies a tenant ID corresponding to the specified user ID from the user information stored in the user information storage unit 153. The user management unit 133 notifies the authentication/authorization unit 131 of the specified tenant ID.

In step S65, the authentication/authorization unit 131 makes a license information acquisition request to the license management unit 134 by specifying the tenant ID and the service name. The license management unit 134 specifies license information corresponding to the specified tenant ID and the service name from the license information stored in the license information storage unit 154. The license management unit 134 notifies the authentication/authorization unit 131 of the specified license information.

In step S66, the authentication/authorization unit 131 issues an authorized token described later by using the obtained service name and the license information. The authentication/authorization unit 131 returns the issued authorized token to the translation service delivery device 32.

Here, in the sequence diagram of FIG. 10, the authorized token issued by the authorized token acquisition API in step S61 is only an authorized token related to the translation service provided from the translation application, and cannot obtain an authorized token related to another service.

Moreover, in the sequence diagram of FIG. 10, a user who can use the authorized token acquisition API in step S61 is limited by specifying the tenant ID from the authentication ticket and then specifying the license information from the tenant ID and the service name. Furthermore, the authentication/authorization unit 131 checks whether there is a valid license of the translation service in a tenant to which the user belongs based on the obtained license information, and performs a process of returning the authorized token thereto when the valid license is present.

FIG. 12 is a flowchart illustrating an example of a process of the authentication/authorization unit when issuing an authorized token. In step S81, the authentication/authorization unit 131 performs the application authentication by using the application ID and the application password, and determines whether the application ID and the application password are right in step S82.

When the application ID and the application password are right, the authentication/authorization unit 131 verifies the authentication ticket, and determines whether the authentication ticket is valid. When the authentication ticket is valid, the authentication/authorization unit 131 obtains user information (tenant ID) in step S83, and obtains license information in step S84.

In step S85, the authentication/authorization unit 131 determines whether to have a license valid to the obtained license. When a valid license is present, the authentication/authorization unit 131 generates an authorized token in step S86, and returns the authorized token thereto. In contrast, the authentication/authorization unit 131 returns an error when the application ID and the application password are not right; the authentication ticket is not valid in step S82; and there is no license valid to the obtained license in step S85.

<<Authorized Token>>

As discussed above, the authorized token according to the embodiment can be configured in a variety of forms. In step S41, the scanner application 206 determines whether to have an authority to utilize a function of the image forming apparatus 12 by different processes depending on the configuration of the authorized token. A description is given below of a process of determining whether to have an authority to utilize a function of the image forming apparatus 12 depending on a configuration of the authorized token while illustrating the configuration of the authorized token.

FIG. 13 is a configuration diagram illustrating an example of the authorized token. The token illustrated in FIG. 13 includes authorization information and information obtained by encrypting the authorization information. The authorization information includes an identifier, request time, an expiration data, a service name, and a contract category. The contract category is information indicating whether a license is a trial or an effective contract. As discussed above, the information obtained by encrypting the authorization information is used for checking that the authorized token was issued from the ID management service unit 220.

In the authorized token configured as illustrated in FIG. 13, for example, the process in step S41 is performed as illustrated in FIG. 14. FIG. 14 is a flowchart illustrating an example of a process of determining whether to have an authority to utilize a function of the image forming apparatus 12.

In step S101, the scanner application 206 determines whether or not the contract category is the trial. When the contract category is the trial, in step S104, the scanner application 206 determines that there is an authority to use the scanner application 206 and the OCR application 207 without respect to presence or absence of a license of the scanner application 206 and the OCR application 207. In other words, when the contract category is the trial, the scanner application 206 determines that the authority to use the scanner application 206 and the OCR application 207 is present even when the license of the scanner application 206 and the OCR application is absent.

When the contract category is not the trial but the effective contract, in step S102, the scanner application 206 determines whether to have the license of the scanner application 206 and the OCR application 207. When the license of the scanner application 206 and the OCR application 207 is present, in step S104, the scanner application 206 determines that the authority to use the scanner application 206 and the OCR application 207 is present.

When the license of the scanner application 206 and the OCR application 207 is absent, in step S103, the scanner application 206 determines that the authority to use the scanner application 206 and the OCR application 207 is absent.

According to the process in the flowchart illustrated in FIG. 14, when the contract category of the translation service is the trial, the image forming apparatus 12 authorizes the use of the scanner application 206 and the OCR application 207 without the license of the scanner application 206 and the OCR application 207. Moreover, when the contract category is the effective contract, the image forming apparatus 12 determines whether to authorize the use of the scanner application 206 and the OCR application 207 depending on whether or not to have the license of the scanner application 206 and the OCR application 207.

For example, when the contract category of the translation service is the effective contract, the image forming apparatus 12 does not permit the use of the scanner application 206 and the OCR application 207 without the license of the scanner application 206 and the OCR application 207. Accordingly, a user needs to separately purchase the license of the scanner application 206 and the OCR application 207 when the contract category of the translation service is the effective contract. Here, the image forming apparatus 12 does not permit the use of the translation service when a license agreement of the translation service is not made or expired.

As stated above, the image forming apparatus 12 can operate differently from the contents of the license of the functions (scanner application 206, OCR application 207) of the image forming apparatus 12 based on the contents (contract category) of the authorized token issued from the ID management service unit 220.

In other words, a provider that provides the translation service can change the operation of the application installed in the image forming apparatus 12 based on the contents of the authorized token issued by the ID management service unit 220.

FIG. 15 is a configuration diagram of another example of the authorized token. The authorized token illustrated in FIG. 15 includes authorization information and information obtained by encrypting the authorization information. The authorization information includes an identifier of the authorization information, request time, an expiration date, and an available function name. The available function name shows a function name available for the image forming apparatus 12.

The scanner application 206 refers to the available function name of the authorized token in FIG. 15, and determines that there is an authority to use the scanner application 206 and the OCR application 207 when the scanner application 206 and the OCR application 207 are set to be the available function. Moreover, when the scanner application 206 and the OCR application 207 are not set to be the available function in the authorized token, the scanner application 206 separately determines whether to have a license of the scanner application 206 and the OCR application 207.

For example, the image forming apparatus 12 does not permit the use of the scanner application 206 and the OCR application 207 when the license of the scanner application 206 and the OCR application 207 is absent. The image forming apparatus 12 permits the use of the scanner application 206 and the OCR application 207 when the license of the scanner application 206 and the OCR application 207 is present.

The available function name of the authorized token in FIG. 15 is, for example, set as illustrated in the following. FIG. 16 is a configuration diagram illustrating an example of a service license/function correspondence table utilized by the ID management service unit for generating an authorized token. In the service license/function correspondence table of FIG. 16, for example, a contract category and a function name are associated with each service name of the translation service.

The contract category is similar to the contract category in FIG. 13. Furthermore, the function name is similar to the available function name in FIG. 15. The ID management service unit 220 can specify a function available for the image forming apparatus 12 set to be associated with the service name and the contract category by utilizing the service license/function correspondence table of FIG. 16.

For example, when the contract category of the translation service is the trial in the service license/function correspondence table of FIG. 16, the scanner application 206, the OCR application 207 and a monochrome print application are set to be the available function name of the authorized token. In the trial in the service license/function correspondence table of FIG. 16, when the contract category of the translation service is the effective contract (paid), the scanner application 206, the OCR application 207 and the monochrome print application and a color print application are set to be the available function name of the authorized token.

Thus, when the contract category of the translation service is the effective contract (paid), the scanner application 206 of the image forming apparatus 12 separately needs to determine whether to have a license of the OCR application 207. Here, to create the service license/function correspondence table illustrated in FIG. 16, an operator of the service platform delivery service 40 may request a provider who provides a service such as the translation service to submit an application as illustrated in FIG. 17.

FIG. 17 us a schematic diagram illustrating an example of the application. The application in FIG. 17 is to apply an available function for each contract category. The operator of the service platform delivery system 40 creates the service license/function correspondence table setting the function name (available function name) for each contract category of the service name of “translate” as illustrated in FIG. 16 in response to the application as illustrated in FIG. 17.

According to the authorized token illustrated in FIG. 15, when the contract category of the translation service is the trail, the image forming apparatus 12 permits the use of the scanner application 206 and the OCR application 207 even if the license of the scanner application 206 and the OCR application 207 is absent. Moreover, when the contract category of the translation service is the effective contract, the image forming apparatus 12 determines whether to permit the use of the OCR application depending on whether to have the license of the OCR application.

For example, when the contract category of the translation service is the effective contract, the image forming apparatus 12 does not permit the use of the OCR application 207 without the license of the OCR application 207. The user needs to separately purchase the license of the OCR application when the translation category of the translation service is the effective contract.

As discussed above, the image forming apparatus 12 can operate differently from the contents of the license of the functions (scanner application 206, OCR application 207) of the image forming apparatus 12 based on the contents (available function name) of the authorized token issued from the ID management service unit 220.

In other words, a provider that provides the translation service can change the operation of the application installed in the image forming apparatus 12 based on the contents of the authorized token issued by the ID management service unit 220.

FIG. 18 is a configuration diagram illustrating another example of the authorized token. The authorized token illustrated in FIG. 18 differs from the authorized token in FIG. 15 in that the available name in FIG. 15 is replaced by a role name. The role name shows a type of a user such as a tenant administrator, a general user or the like. The scanner application 206 sets a function available for the type of user shown by the role name by associating the function with the role name.

The scanner application 206 refers to the role name of the authorized token in FIG. 15, and determines that there is an authority to use the scanner application 206 and the OCR application 207 when the scanner application 206 and the OCR application 207 are set to be the function available for the type of user shown by the role name. Moreover, when the scanner application 206 and the OCR application 207 are not set to be the function available for the type of user shown by the role name in the authorized token, the scanner application 206 separately determines whether to have a license of the scanner application 206 and the OCR application 207.

For example, the image forming apparatus 12 does not permit the use of the scanner application 206 and the OCR application 207 when the license of the scanner application 206 and the OCR application 207 is absent. The image forming apparatus 12 permits the use of the scanner application 206 and the OCR application 207 when the license of the scanner application 206 and the OCR application 207 is present.

According to the authorized token illustrated in FIG. 18, when the role name indicates, for example, a tenant administrator, the image forming apparatus 12 permits the use of the scanner application 206 and the OCR application 207 even if the license of the scanner application 206 and the OCR application 207 is absent. Moreover, when the role name indicates, for example, a general user, the image forming apparatus 12 determines whether to permit the use of the scanner application 206 and the OCR application depending on whether to have the license of the scanner application 206 and the OCR application 207.

For example, when the role name indicates the general user, the image forming apparatus 12 does not permit the use of the scanner application 206 and the OCR application 207 without the license of the scanner application 206 and the OCR application 207. The user needs to separately purchase the license of the scanner application 206 and the OCR application when the role name is the general user.

As discussed above, the image forming apparatus 12 can operate differently from the contents of the license of the functions (scanner application 206, OCR application 207) of the image forming apparatus 12 based on the contents (role name) of the authorized token issued from the ID management service unit 220.

In other words, a provider that provides the translation service can change the operation of the application installed in the image forming apparatus 12 based on the contents of the authorized token issued by the ID management service par 220.

The information processing system 1 of the present embodiment can unify the management of the authority to utilize the service provided for the image forming apparatus 12 because the service platform delivery system 40 the authorized token as stated above.

<<Details of Another Example of Process of Image Forming Apparatus when Executing Job>>

In the process of the sequence process illustrated in FIG. 9, the process of the controller in steps S38 through S42 may be performed, for example, as illustrated in FIG. 19. FIG. 19 is a sequence diagram of another example illustrating details of a process of the image forming apparatus when executing a job.

In step S51, the job execution management unit 204 is requested to execute a job in which an authorized token is specified from the JavaScript 203. In step S152, the job execution management unit 204 requests the authorized token verification unit 205 to verify validity of the authorized token by specifying the notified authorized token. The authorized token verification unit 205 verifies the validity of the authorized token as illustrated in step S39, and returns a result of the validity verification to the job execution management unit 204.

In step S153, the job execution management unit 204 confirms whether to have an authority to utilize the function of the image forming apparatus 12 needed to use the translation service by using a correspondence table between an API and a necessary function as illustrated in FIG. 20.

FIG. 20 is a diagram illustrating an example of a correspondence table between the API and the necessary function. In the correspondence table illustrated in FIG. 20, the necessary function of the image forming apparatus 12 is associated with each API showing a type of service. For example, in the correspondence table in FIG. 20, the scanner application and the OCR application are set to be the function of the image forming apparatus 12 necessary for the API of “scan+OCR.”

The job execution management unit 204 determines whether to have the authority to utilize the function of the image forming apparatus 12 needed to use the translation service by the authorized token as described above. When the authority to utilize the function of the image forming apparatus 12 is present, the job execution management unit 204 requests the scanner application 206 to execute the job in step S154.

The scanner application 206 executes the job in step S155. The scanner application 206 returns an execution result of the job to the job execution to the job execution management unit. Moreover, the job execution management unit 204 returns the execution result of the job to the translation application and the JavaScript 203, and reflects the execution result on the screen displayed by the browser.
